This utility model relates to the field of single crystal furnace leveling technology, and in particular to a single crystal furnace chamber leveling mechanism, comprising a mounting base, multiple support rods, multiple support rings, a mounting plate, multiple nuts, and multiple adjusting components. The mounting base has first mounting holes at each of its four top corners and mounting cavities at each of its four side edges. Each support rod has a second threaded sleeve threadedly connected to its outer wall, and the second threaded sleeve is fixedly connected to the corresponding first mounting hole. This application fixes the mounting base within a concrete base. The adjusting components drive the support rods to rotate via worm gears and other components. The threaded connection between the support rods and the second threaded sleeves allows for the raising and lowering of the support rods, thereby adjusting the levelness of the mounting plate. This design is independent of the precision of the concrete base and allows for real-time adjustment of the mounting plate during installation, ensuring the levelness of the single crystal furnace chamber.

The utility model belongs to the technical field of honeycomb paperboard pressing, and particularly relates to a honeycomb paperboard plane pressing mechanism which comprises a fixing frame internally provided with a conveying belt and further comprises two guide assemblies symmetrically arranged above the conveying belt and arranged between two movable plates. The moving plate is fixedly connected with the guide assembly through a smooth rod, the moving plate moves to drive the guide assembly to move horizontally through the smooth rod, the pressing belt is movably connected with the moving frame, the top end of the moving frame is connected with the output end of the air cylinder, and the moving frame and the pressing belt are driven to move vertically through the air cylinder; the paperboard guiding device can guide paperboards with different sizes, and can press the paperboards with different thicknesses.

The application discloses a greenhouse vegetable planting soilless culture system and relates to the technical field of vegetable planting. The technical scheme comprises a device main body, a culture tank fixedly connected to the upper portion of the device main body, a circulating pipeline arranged on one side of the culture tank, a flow guide cavity fixedly connected to the upper portion of the circulating pipeline, a filter shell fixedly connected to the lower portion of the flow guide cavity, a cleaning shell fixedly connected to the top of the flow guide cavity, and a second motor arranged in the cleaning shell. In the application, the second motor is started to drive the first rotating rod and the second rotating rod to rotate synchronously, the second rotating rod is rotated to drive the filter cartridge to rotate, the filter cartridge is rotated under the action of centrifugal force to promote the separation of impurities in the nutrient solution, the separated impurities are attached to the inner wall of the filter cartridge, the first rotating rod is rotated to drive the cleaning rod to rotate, the cleaning rod is rotated to clean the separated impurities on the surface of the filter cartridge, and the vibration mechanism drives the cleaning rod to vibrate during the cleaning process, so that the scraped impurities are quickly dropped and gathered at the bottom of the filter cartridge.

The utility model relates to the technical field of airport earthwork filling, and particularly discloses a levelness-adjustable pithead positioning mechanism which comprises a pithead positioning ring, an annular positioning plate, a positioning pin and an adjusting bolt, the annular positioning plate is fixedly sleeved at the bottom of the outer side ring wall of the pithead positioning ring, a positioning hole and a threaded hole are arranged on the annular positioning plate, and the positioning pin is arranged in the positioning hole. The adjusting bolts are arranged in the threaded holes in a threaded connection and penetrating mode and abut against the ground in a matched mode, the adjusting bolts are used for adjusting the levelness of the annular positioning plate, and the positioning pins penetrate through the positioning holes to fix the annular positioning plate to the ground. According to the utility model, the levelness adjustment and stable fixation of the pithead positioning ring can be realized, the position of the pithead positioning ring can be ensured not to deviate or incline in the process of excavating a test pit in the pithead positioning ring to carry out a detection test of an irrigation method, the pithead positioning ring can be always ensured to be horizontally placed and fixed, and the working efficiency is improved. Therefore, the detection precision and the detection progress of the test are improved, and the test pit size meets specification requirements.

This utility model discloses a table for sorting cigarettes, which includes a support body and a tabletop supported by the support body. One side of the tabletop is connected to the discharge end of the sorting conveyor belt, and the adjacent other side is provided with a bag opening receiving groove. The bottom of the bag opening receiving groove is connected to a bag opening opening auxiliary piece that matches the long side of the bag opening. When using the table, one operator opens the bag, inserts the bag opening opening auxiliary piece into the bag opening, and lifts the top of the bag to fully open the bag opening. Another operator moves the sorted cigarettes to the front of the bag opening on the tabletop, and then pushes the cigarettes into the bag to complete the packaging. It is very convenient to use.
